Abstract
A transfer arrangement comprising a syringe (110) having a side wall defining a cavity (116) which is sealed by plunger (114), a needle (119) being connected to a second syringe end (113), an adaptor (124) having a first adaptor end (121) connecting to the second syringe end (113), the adaptor (124) extending about the needle (119), second adaptor end (123) having a luer connector (126), and a transfer member (128) having first and second transfer member ends (131, 133) with the first transfer member end (131) being connected to the second adaptor end (123) while the second transfer member end (133) receives the neck of a vial (130).
Core Innovation
The document describes a transfer arrangement using a syringe having a side wall defining a cavity, with first and second syringe ends. The first syringe end is sealed by a plunger mounted within the syringe, a staked in needle is connected to the second syringe end, and a back stop is connected to the syringe proximate the first syringe end.
An adaptor is provided with first and second adaptor ends. The first adaptor end is designed to connect to the second syringe end, and the adaptor extends about the staked in needle to prevent access thereto. The second adaptor end has a luer connector for connecting to a transfer member.
The transfer arrangement further includes a transfer member having first and second transfer member ends. The first transfer member end is connectable to the second adaptor end, and the second transfer member end is arranged to receive a neck of a vial. In the described reconstitution/transfer arrangement, the structure supports moving liquid between containers while protecting the needle from contamination and damage during detachment and injection.
Claims Coverage
The independent claim covers a transfer arrangement with four main inventive components: a syringe sealed by a plunger and equipped with a staked in needle, a back stop, an adaptor with a luer connector that extends about the needle to prevent access, and a transfer member configured to receive a vial neck. The dependents add further mechanical connectivity and explicitly include a vial connected to the transfer member end.
Syringe with plunger-sealed open end and staked in needle
A syringe having a cavity, first and second syringe ends with the first syringe end being open, a plunger mounted within the syringe to thereby seal the first syringe end, and a staked in needle connected to the second syringe end.
Back stop connected to the syringe proximate the plunger-sealed end
A back stop connected to the syringe proximate the first syringe end.
Needle-excluding adaptor extending about the staked in needle with luer connector
An adaptor having first and second adaptor ends, the first adaptor end being designed to connect to the second syringe end, the adaptor extending about the needle to prevent access thereto, and the second adaptor end having a luer connector.
Transfer member receiving a vial neck
A transfer member having first and second transfer member ends, the first transfer member end being connectable to the second adaptor end, and the second transfer member end being arranged to receive a neck of a vial.
Plunger rod connected to the plunger
The transfer arrangement further includes a plunger rod connected to the plunger.
Vial connected to the end of the transfer member
The transfer arrangement further includes a vial connected to the end of the second transfer member.
Overall, the claim coverage is directed to a transfer arrangement combining a plunger-sealed syringe with a staked in needle, a back stop, a needle-access-preventing adaptor with a luer connector, and a transfer member arranged to receive a vial neck; dependent refinements specify a plunger rod linkage and expressly provide a vial connected to the transfer member end.
Stated Advantages
prevent access to the staked in needle
Documented Applications
A reconstitution/transfer arrangement for transferring diluent into a vial containing a dry component, mixing, aspirating back, and detaching for injection while protecting the needle from contamination and damage.
